Why convert OPUS to AAC?

  • Play saved WhatsApp and Telegram voice messages in native apps instead of a third-party player.
  • Drop audio into iMovie, GarageBand, or Final Cut, none of which ingest Opus.
  • Put files on car USB sticks and older devices whose decoders cover AAC but not Opus.

Tip: Give the AAC room to breathe: converting a 32 kbps Opus voice note to 96-128 kbps AAC keeps the transcode from adding audible damage.
